Wow - you must be older than me.  Thought I had that record.
Bill,
 
Hey, I don't know about that, but here is the first computer I programmed:
 
 
Illiac I

Illiac-I, built at the University of Illinois

Illiac I was the first computer built and owned entirely by a university. It went on line on September 22, 1952. With the computing power of a modern-day handheld calculator, Illiac had 2,800 vacuum tubes and weighed 10,000 pounds. It was more than 10 ft long, 2 ft high, and 8 ft high, with a 5k main memory and 64k Drum memory. The engineers and scientists continued working on Illiac, which , and by 1956, it had more computing power than all of the systems at Bell Labs.

Darn, I lied again.  Actually, It was the IBM 604 wired program computer:

The 604 electronic calculator, introduced in 1948, was designed primarily for commercial calculations.

A program:

The 604 arithmetic unit contained about 1400 electron tubes, used to implement memory (37 decimal digits), an counter/accumulator of 13 (decimal) positions, and control circuits. The basic operations (listed in Table 1) could be used under control of a hard-wired program provided by the user. The connections were made by hand on a pluggable patch panel. Maximal 60 program steps could be wired on a single panel. For iterative procedures, a program could be made to include loops.

 

It took two program panels and two passes to compute correlations........

Now you know why I am Grayhawk.
